Conteúdo: | The tillage practice of soil bed formation as a mean of improving the superficial drainage of soil was investigated. This study was conducted in two different experiment at Southeast Purdue Agricultural Center (SEPAC) Butlerville, Indiana. The objective of the first experiment was to study the energy requirements for soil formation and also to evaluate the soil bed profiles at three different tractor seeds, with without subsoiler, using a Ford 8000 diesel tractor and a John Deere 990 Bedder equipament. The parameters studied were power, fuel consumption and slippage. The objective of the second experiment was to evaluate the soil beds as compared to spring chiselling, spring plowing and no-till in relation to the agronomic aspects (soil temperature and moisture content, plant growth, grain yield under continuous corn). Profiles were measured of the soil beds and spring plowing treatments (conventional systems) at different stages of seedbed preparation, during the growing season and after harvest. This experiment was performed in conjunction with the study of "the Effect of Tillage and Crop Rotation and Corn and Soybean Yields" being conducted by the tillage group of Purdue University. The results showed the energy requirements for soil bed formation were lower for the treatments without subsoiler than for the ones with subsoiler, based on tractive efficiency and also the beds were more stable in those treatments. The power ranged from 33.10 kw to 70.25 kw and the fuel consumption from 5.91 to 6.53 (...)
